- v Specification of Letters Patent. o Patented Sept. 2, 1913- v Application med'iuay 24,1912. Serial No. 699,600.

To all whom fnlay concern Be it known that we, WILLIAM the following is a. specification.

-O ur invention relates more particularly to-f i0 yp r e e. n ee h lik p ntineline by line upon a-paper' sheet; and 1 our: improvementfhas for its Object to:indi'oatef during a plurality. of sheet positionsthe: distance from theicurrent printing 1 point to f the edge of the sheet, or to a point 1 a known distance therefrom,- and this auto-i regardless of the lengh of the matically sheet, without care or thought on the part of the operator in advance of the operation of the device; Portions of our mechanism are adapted to be used'in other combinations for.

similar sheet-position-indicatingc purposes.

We attain1 our object by means of. the

mechanism illustrated-in the accompanying F'gurevl is an end view of our-.device,- partly-in cr'Osesect-io'n, as applied to a type-:

writing-machine, but with certain welllmaw'n rtions of thesaid machine omitted;;an, Fig. 2 is a front view of the same,

but witlr'cefiain portions of the typewriting mac cp'artly: broken away. v I 'yni ols 'of reference refer to similap palrtsiintheiseveral figures.

of solenoi now "this. structure as .a-

supported on the. iece 47, ;Whihconductor 31. These feelers are preferably J. NE'IDIG I and CLINTON B. S'1'E\VAR'I.,,Citizens-Ofthe United States, residi'ngat Madison int-hle' county of .Dane and State of Wisconsin,; have inventeia newand useful Improve-Y ment, in"Type.Writing Machine s,. of which 1 made of a very thin resilient material, and each is a conductor. From each of the feelers 28 leads an insulated wired-k into and throughthe cable'53 to a suitable'series s 43, except that the first feeler,

or the one-nearest the paper-table 8, has its insulated .Wirelead to the source of current A instead of to'a solenoid directly; Th at is 10 say, theinsulated .wire a leads. to the first solenoid in the-series, shown in partial croxsection Fig. 1, and the nextvwi-re tot-he next-"solenoid, andso on to the-last,' or 'wire 7c. These solenoids aremounted on the transversely extending plate which is attached to the front plate 58 or convenience.. Each has the usual core surrounded by the usual coil of wire,'the wire being connected in each case atone end with one. of i the wires in the cable 53, and at the other with the wireA. Each solenoid is supplied 4 with the reciprocating plunger 54 having thereon the stop 61 to prevent-complete contact between. the plungerand the ooreand thus obviate the necessity of overcoming the force of the residual niagnetisrn that might' be latent in the magnet or'solenoid. To

this plunger is connected by means of the pin 57 the index-carriferti journaled'upon the pin or shaft56, the said shaft being sup-.

ported at the ends by the support 62 on the plate 55, on whichis the bar 60 adapted to serve as a stop-for the carrier 6, The shaft 5 56 and stop 6O Ina. conveniently be-comm'on to all the s'olenoi sin the series. One portion of. the face of the carrier 6 is supp ied with 'indices-adapted to be raised into view opposite apertures in the front plate 58 of the machine, asshown in Fig. 2; where the carriers are shown/as havm indicating position, as against the non-in icating-position' shown in- Fig. l. The insulated wire At, latter being tapped into by insulated wires "from each of the solenoids, is connected by means of the condii'et-or A 'withithe conduct-ingiswitch-pieiie A, the switch-lever A, 1

and the, switch- "fece A, all of which are insulated from t thence leads to the source of current A.

- The mechanism operates as follows: 'A 4 'sheet'ot paper is placed upon the paper table 8 and advanced around the platenrollinthe usual way, undere supporting plate 55, and; I
